RW SERIES
RW Series resistors are manufactured on an exclusive
automated system, resulting in significant cost savings.
Ceramic core results in performance levels far superior to
conventional fiberglass cores, especially in regards to
overload capability, TCR, noise characteristics, and load life
stability. Coating is flame resistant and offers excellent
moisture and solvent resistance.
ꢀ Excellent performance at economy prices
ꢀ Inherent stability due to all-welded wirewound construction
ꢀ Wide resistance range: 0.01Ω to 25KΩ
ꢀ Standard tolerance is 5% (2% and 10% available)
ꢀ Available on exclusive SWIFTTM delivery program
ꢀ Available on horizontal Tape & Reel (1W-10W), or
vertical Tape & Reel (1W-3W)

TYPICAL PERFORMANCE CHARACTERISTICS
OPTION FF FUSE RESISTOR APPLICATION GUIDE
1. Opt. FF fusible version is available from 0.1Ω - 2.4K (RW1=1.2K max)
2. Fault level must be suitable to safely open the resistor. Option FF parts
are desgned to blow within 20S at 15x rated power if ≥1Ω, 20x if<1Ω
(preferable if fault level is double this level to ensure quick fusing time).
3. Maximum fault must not exceed 200x W rating, or voltage rating,
whichever is less (increased levels avail).
Temperature Range
-55°C to +275°C
1Ω and above: 100ppm/°C
0.05 to 0.99Ω : 300ppm/°C
Below 0.05Ω : 600ppm/°C
Temperature Coefficient
4. For customized fusing, complete RCD’s fuse questionnaire, or advise the
desired fusing wattage/current, min/max blow times, continuous power, surge
reqts, ambient temp, physical constraints, fault voltage, inductance, etc.
5. Fuse types shouldn’t be mounted in contact with other components or PCB.
6. Residual resistance is ≥100x initial value after fusing.
Insulation Resistance
Marking
1000 Megohms
Color band (or alpha-numeric)
with res.value and tolerance
7. Verify selection by evaluating under the full range of fault conditions.
Place resistors inside a protective case when testing under overload.
